JOHN HENRY, OF GRAND FORKS, NORTH DAKOTA.

GRAIN-DOOR FOR CARS.

Specification of Letters Patent.

Application filed September A27, 1909. Serial No. 519,869.

To all whom t may concern:

Be it known that I, JOHN HENRY, citizen of the United States, residingat Grand Forks, in the county of Grand Forks and State of North Dakota,have invented new and useful Improvements in Grain-Doors for Cars, ofwhich the following is a specilication.

My invention pertains to removable grain doors for cars; and itcontemplates the provision of a door that is retained in serviceposition by means not liable to be aected by the contents of the car,and is adapted to be taken out or removed by merely raising one of itsends.

The invention will be best understood by reference to the followingdescription when taken in connection with the accompanying illustrationof specific embodiments thereof, while its scope will be moreparticularly pointed out in the appended claim.

In the drawings: Figure l is a view showing in dotted lines the mannerof taking out the door by raising one end thereof. Fig. 2 is a sectiontaken through the horizontal center of the door per se. Fig. 3 is ahorizontal section taken through the door casing. Fig. 4 is a horizontalsection illustrating a modified way of providing the posts of the doorcasing with flanges for the engagement of the securing means on thedoor. Fig. 5 is a view showing a number of superposed doQrs constructedin accordance with my invention and adapted to be removed in the mannerstated, one after another.

Referring by letter to the said drawings, andmore particularly to Figs.l to 3 thereof: A A are the posts of the door casing, on which are fixedcorner irons having flanges B projecting into the opening between thedoor osts. I would have it understood,y however, that the said flangesmay be provided in any other manner consonant with the purpose of myinvention, as, for instance, by grooving the posts in the manner shownin Fig. 4 to form flanges, this mode of providing a flange B4L on eachpost A4 being especially expedient when the posts are-made of steel, andbeing advantageous inasmuch as the flanges do not project into thedoorway.

C is the door, and D D are the fasteners carried by the door and havingtheir outer portions separated by intervening spaces from the face ofthe door, and therefore, adapted to engage the outer sides of theflanges and secure the door in its service position. The said fastenersD are preferably fixed to and extend endwise beyond fixed projections Eon the face of the door, at points near the ends of the door and at oradjacent the horizontal center thereof, and, when the door is in workingposition, the outer edges of the said fixed projections E are separatedby intervening spaces from the opposed edges of the flanges B on theposts A.

By virtue of the construction described, it will be observed that thedoor is adapted to be taken out of the doorway by merely cant- 'ing thedoor asone piece vertically so that the fasteners D thereon are enabledto clear the flanges B when the door is moved in the direction of itsthickness. The door may as readily be replaced in the doorway andfastened to thecasing by simply reversing said operation. It will alsobe observed that in service the face of the door bears against the innersides of the door posts, and completely isolates the flanges on theposts and the fasteners on the door from the contents of the car, withthe result that such contents is efl'ectually prevented from interferingwith the raising of the door or the movement of the fasteners relativeto the flanges.

In Fig. 5, I illustrate a number of small doors C adapted to besuperposed to close a door-way, and each adapted to be taken out of thedoor-way by raising one of its ends. The said doors C are respectivelyprovided with projections E- and fasteners D, and are therefore adaptedto cooperate with the flanges B on the postsA in Fi 5., in the samemanner that the door C o' Fig. 1 cooperates with the flanges B on theposts A in said figure.

While I have shown and described certain within the body and flatagainst the inner )Y posed edges separated from said edges byintervening spaces suciently llarge to permit of the door being oanted,and fasteners attached to the door part that rests between the opoftheflanges and having end portions extending outward beyond the edges ofsaid dooi` part and lapped against the outer sides of the flanges ontheh door 1 posts.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witmessesi JOHN HENRY. Witnesses:
